Consider the following set of processes with the length of the CPU burst time given in milliseconds:

CPU Burst

The processes are assumed to have arrived in order P1, P2, P3, P4, P5 all at time 0. What is the waiting time of process P4 for Shortest Job First (SJF), non-preemptive priority scheduling, and Round Robin (Quantum=1) scheduling algorithms respectively?

Consider the following statements and choose the correct one:
(A) Job schedulers select processes from the pool and load them into memory for execution.
(B) Short term scheduler selects among the processes that are ready to execute and allocates the CPU to one of them.
